I need the answers for both a and b so thats why 61 points are up for grab

Answer:

The question seems to be incomplete, so i will think that this is a linear equation, where we can find the velocity at which she moves, and also her initial position.

A linear relationship can be written as:

y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

In this case we have two points:

"After 2 minutes, she was 100 steps from the bottom floor."

this can be represented with the point: (2min, 100 steps)

" After 5 minutes she was 196 steps from the bottom floor"

This can be represented with the point (5min, 196 steps)

With this, we can find the slope of this equation:

a = (196 steps - 100 steps)/(5min - 2min) = 96steps/3min = 32 steps/min

This means that she does 32 steps in one minute.

Then we can write her positon equation as:

y = (32steps/min)*x + b

where x represents the time, and b is her initial position.

If we replace x by 2 min, and y for 100 steps, we get:

100steps = (32steps/min)*2min + b

100 steps = 64 steps + b

100 steps - 64 steps = b = 36 steps.

This means that she started to take the stairs 36 steps from the bottom floor.

Answer:

$10800

Step-by-step explanation:

$12000 is the original price so let's set that as 100%. Since there's a 10% discount, you have to find out the 90% soo.

100% - $12000

90% - $12000 x 90/100 = $10800

Answer:

28 pizzas can be bought

Step-by-step explanation:

you have to find the unit rate of the pizzas.

so 135 divided by 15 which is 9

and then you divide 252 by 9

It is found that 28 pizzas can be bought with 252 dollar.

There is an independent quantity, and a quantity that depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called the rate of increment of dependent quantity per unit increment in independent quantity.

We have been given amount of money spent on a pizza for club activities varies directly with the number of pizzas bought.

We need to find the unit rate  of the pizzas

Unit rate = Total amount/ Number of pizzas

Unit rate = 35/15

Unit rate = 9

Also,Unit rate = 259/13

Unit rate = 28

Therefore, 28 pizzas can be bought.

Answer:

it will take her 40 seconds to finish the race.

3/8 per minute, would make it 1/8 every 20 seconds. since she only has 2/8 of a mile left to go, 20 seconds +20 seconds = 40 seconds

(if you needed how long it takes her to run the whole race, it's 2 minutes 40 seconds, which would make her the fastest mile runner in the world)

Answer:

y = 12x-15

Step-by-step explanation:

The equation of a line is given by :

[tex]y=mx+c[/tex]

Where

m is slope and c is y-intecept.

Here, the slope is 12 and y-intercept is -15.

Then the equation is :

y = 12x+(-15)

or

y = 12x-15

Hence, the required equation for the line is "y=12x-15".

Answer:

The first statement is a lie, second and third statement is true.

Step-by-step explanation:

Consider the provided information.

For two similar triangles, if the scale factor is a : b, then the ratio of their perimeters will be a : b.

For two similar triangles, if the scale factor of a : b, then the ratio of their areas will be [tex]a^2 : b^2[/tex].

For two similar triangles, if the scale factor is a : b, then the ratio of their altitudes will be a : b.

It is given that the ratio of perimeters is 6:1 which is incorrect as the ratio should be 3:1.

It is given that the ratio of areas is 9:1 which is correct because [tex]3^2 : 1^2=9:1[/tex].

It is given that the ratio of the altitude is 3:1 which is correct.

Hence, the first statement is a lie, second and third statement is true.

Step-by-step explanation:

if we tip/tax  6% of 156.67 we will do:

156.67*(6/100)=9.40 this is the amount of tip

156.67+9.40=166.07

Answer:

b = 6

Step-by-step explanation:

a² + b² = c²

8² + b² = 10²

8² + b² - 8² = 10² - 8²

b² = 100 - 64 = 36 = 6²

Step-by-step explanation:

Answer:

Step-by-step explanation:

The probability of getting 6 the first time and an even number the second time is 1/12.

probability is the quantification of possibilities in numbers.

(1) probability of rolling a 6 for the first time:

total possible outcomes = (1,2,3,4,5,6) =6

sample space = 1

probability of getting 6 = sample space/total possible outcomes

probability of getting 6 = 1/6

2)probability of getting an even number

total possible outcomes will be (1,2,3,4,5,6)

sample space  =  (2,4,6) ie 3

probability of this = 3/6 = 0.5

total probability = 1/6*0.5 = 1/12

therefore,

The probability of getting 6 the first time and an even number the second time is 1/12.
